<Features> 1. Lightweight and compact, taking up minimal piping space. 2. Ideal as an ON-OFF valve due to its pneumatic ball valve design. 3. The valve body is made of stainless steel with a precision casting finish, offering excellent corrosion resistance. 4. The actuator features a double piston with a rack and pinion mechanism, making it an efficient 90° rotating actuator. 5. The actuator connects directly to the valve body and can be mounted with just two bolts.

The simple mechanism makes it extremely compact and lightweight.

<Features> 1. Lightweight and compact design ideal for automated systems. The actuator incorporates a rotational mechanism linked to the piston, and uses a simple holder for attachment to the ball valve. The actuator body is made of aluminum alloy, making it lightweight. 2. The ball valve body and actuator can be detached using two hex socket screws. In cases where the actuator cannot be installed due to tight spaces, complex piping, or other equipment, the ball valve body can be installed first, allowing the actuator to be attached afterward. 3. The actuator can be mounted in any direction, with a rotation range of 360° in 90° increments. 4. The gland packing area can be inspected and tightened even with the actuator attached. 5. Manual operation is also possible. Additionally, limit switches for confirming valve opening and closing can be installed. 6. All metal parts of the ball valve are made of stainless steel. PTFE-based resin and fluororubber O-rings are used for the gland packing and sealing materials.

It is a valve with low fluid resistance and excellent operability.

A valve that controls fluid by rotating a spherical, hemispherical, or cylindrical valve body, allowing for full bore capability with a flow path that matches the inner diameter of the piping. Additionally, there are no obstacles in the fluid within the valve diameter, making it less likely for vortices or pulsations to occur, resulting in excellent flow characteristics. The simple structure and superior operability of ball valves make them widely used in various fields and applications.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

SPACECOOL Inc., which researches, develops, and sells the radiation cooling material "SPACECOOL" that releases heat into space to achieve zero-energy cooling, will exhibit at the "Jumbo Surprise Exhibition," a comprehensive trade fair for electrical materials and housing equipment, held at Tokyo Big Sight from April 17 (Friday) to April 18 (Saturday), 2026, and at Intex Osaka from April 24 (Friday) to April 25 (Saturday), 2026. This material is a new technology that enables zero-energy cooling by converting heat into infrared radiation and releasing it into space, without using any external power. By implementing it in outdoor air conditioning units and outdoor electrical equipment, it helps suppress internal temperature rises, contributing to stable operation of devices and reduction of air conditioning energy consumption, and is being recognized as a new carbon-neutral technology. Its energy-saving performance has been acknowledged, and this material received the 2025 Energy Conservation Award. When you visit the venue, please stop by our booth. Our booth number is 972 (common for both Tokyo and Osaka). We will continue to work towards expanding the social implementation of SPACECOOL to contribute to the stable operation of outdoor equipment and air conditioning units, as well as to reduce air conditioning energy consumption and CO2 emissions.
